A fast-cutting, 2-1/4" diameter sharpening stone with a friction-fit
rubber clamshell case for secure grip. Made of durable ceramic abrasive,
it has a coarse 180x side that removes nicks and leaves a toothed edge
suitable for most large garden implements, and a fine 600x side for honing
or maintaining an existing edge.
The stone is best used with water as a lubricant, but can also be used
dry. Unaffected by freezing temperatures (even when wet). Its compact
size makes it an ideal carry-along to the woodlot or campsite.
